To a whom it may concern:

Be it known that I, GEORGE XV. BANKER, of Brooklyn, in the county of Kings and State of New York, have invented new and Valuable Improvements in Composite Oils for Lu bricating, &c., of which the following is a specification.

Since the introduction of petroleum and its products for lubricants and other purposes attempts have been made to combine such oils with castor-oil, (which, for slowrunning and heavy machinery, is considered superior to other oils;) but no satisfactory way of combining mineral oils with Castor-oil was discovered until my composite oil wasproduced and patented, March 21, 1882, No. 255,096.

The object of my invention is to produce a composite oil as a new article of commerce,
